Installing engine oil temperature gauge - TJ

Where's the TV?

Does the light interact with the computer in any way?

Yep, on ships our lives depended on guages

It's not necessary to braze it, getting it hot enough to risk an oil vapor flash. I would drain the oil, and solder the fitting on. If you can get your oil pan over 400 when running it and melt solder, you won't need a temp guage to tell you it's toast. I don't know if i would epoxy a sender outside of a plastic pan, it probably has some insulating properties.

Knowing the temperature of the oil in the pan is largely irrelevant. The temperature that matters is the temperature at the outlet of the oil filter and/or cooler ,i.e. the main oil gallery feed.

AC 43-13-1B!

Dry sumps are great if you have an engine designed to be a dry sump engine from the start like a Offenheuser, Fairbanks-Morse, or Pratt and Whitney. The Porsche 911 flat six is the only production car engine of which I am aware that is designed to run a dry sump. Racers dry sump production car based racing engines all the time, but they use a small stacked scavenge pump, such as Weaver Bros. sells, driven by a small Gilmer belt. This is strictly Mickey Mouse thinking for any vehicle not subject to constant maintenance like an actual race car. On something you are going off road with, a dry sump would only be acceptable if the scavenge and pressure pumps were internal to the engine.

Because it is an off-road vehicle, and needs as few wires and gizmos glued to the bottom, as you can get along without. If you do attach a fitting to the pan, at least braze it, so it doesn't fall off.

I have always used dealer filters (difficult to find replacement ones in New Zealand). Can you tell me what the Fram or other filter numbers would be for 4.0 Wrangler?

Thanks. TW

I do want to avoid dropping the pan.

Thanks TW

Well, that is another reason why I was more towards using a sandwich plate to pick-up temperature than the pan. Although the other reason was I don't want low hanging wires on something that I do take off-road in mud and forests.

Going dry sump is not an option at this stage for me (its my daily driver).

Thanks TW

Precisely, I do want to monitor the temperatures but not have low hanging wires.

Thanks TW

I plan on lying under it today in the afternoon and see if there is such a thing already.

TW

Well, if I can avoid a tee it would be preferable. But I am not completely opposed to it. The advantage I have with a sandwich plate is that if the gauge shows the oil temperature does get high enough on off-road trips, then I already have outlet and inlet for putting on a cooler.

What I am opposed to is dropping the pan and drilling a hole in it (low hanging wires).

Thanks for all you time and comments. It has been educational.

On a TJ, the oil pressure sending unit is attached to a gauge on the dash and not an idiot light. I do want to keep that gauge working.

Hey Bill, do you know what oil filter numbers would be compatible for a 4.0 TJ.

Thanks TW

I knew there was a reason why I never bought a Ford....... :-)

TW

Yet you would buy a Jeep, and they do the same thing.

Thanks for the warning. I have '01 TJ, so whats the verdict on that? Is it

Thanks in advance. TW
